Example of rfc1902 module usage

>>> from pysnmp.proto import rfc1902
>>> s = rfc1902.ObjectSyntax(simple_syntax=rfc1902.SimpleSyntax())
>>> s['simple_syntax']['string_value'] = rfc1902.OctetString('foobar')
>>> s
ObjectSyntax(simple_syntax=SimpleSyntax(string_value=OctetString('foobar')))
>>> s.encode()
'\004\006foobar'
>>>
>>> s2 = rfc1902.ObjectSyntax()
>>> s2
ObjectSyntax()
>>> s2.decode(s.encode())
''
>>> s2
ObjectSyntax(simple_syntax=SimpleSyntax(string_value=OctetString('foobar')))
>>>
